Dependencies
- h5py -- to save samples
- Tensorflow 1.2 or later.
Get this code and the data
First things first, clone this repo and get the human3.6m dataset on exponential map format.
git clone https://github.com/una-dinosauria/human-motion-prediction.git
cd human-motion-prediction
mkdir data
cd data
wget http://www.cs.stanford.edu/people/ashesh/h3.6m.zip
unzip h3.6m.zip
rm h3.6m.zip
cd ..
Quick demo and visualization
For a quick demo, you can train for a few iterations and visualize the outputs of your model.
To train, run
python src/translate.py --action walking --seq_length_out 25 --iterations 10000
To save some samples of the model, run
python src/translate.py --action walking --seq_length_out 25 --iterations 10000 --sample --load 10000
Finally, to visualize the samples run
python src/forward_kinematics.py
This should create a visualization similar to this one
Running average baselines
To reproduce the running average baseline results from our paper, run
python src/baselines.py
RNN models
To train and reproduce the results of our models, use the following commands
| model | arguments | training time (gtx 1080) | notes |
|---|---|---|---|
| Sampling-based loss (SA) | python src/translate.py --action walking --seq_length_out 25 |
45s / 1000 iters | Realistic long-term motion, loss computed over 1 second. |
| Residual (SA) | python src/translate.py --residual_velocities --action walking |
35s / 1000 iters | |
| Residual unsup. (MA) | python src/translate.py --residual_velocities --learning_rate 0.005 --omit_one_hot |
65s / 1000 iters | |
| Residual sup. (MA) | python src/translate.py --residual_velocities --learning_rate 0.005 |
65s / 1000 iters | best quantitative. |
| Untied | python src/translate.py --residual_velocities --learning_rate 0.005 --architecture basic |
70s / 1000 iters |
You can substitute the --action walking parameter for any action in
["directions", "discussion", "eating", "greeting", "phoning",
"posing", "purchases", "sitting", "sittingdown", "smoking",
"takingphoto", "waiting", "walking", "walkingdog", "walkingtogether"]
or --action all (default) to train on all actions.
The code will log the error in Euler angles for each action to tensorboard. You can track the progress during training by typing tensorboard --logdir experiments in the terminal and checking the board under http://127.0.1.1:6006/ in your browser (occasionally, tensorboard might pick another url).
